Alexander Leidinger 2e14ff0f41 Say welcome to 'sade', the SysAdmins Disk Editor. It's the fdisk and disklabel part
of sysinstall. So sysinstall may retire now, we have the important non-install part
of it covered.

ATM it doesn't understand GEOM stuff (like mirror, stripe, raid, ...), but patches
to change this and to clean it up internally are more than welcome.
